NARROW-WARE LOOM.

ment in Narrow-VVare Looms; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention relates to looms and particularly to that kind of loomsof the narrowware class known as German looms, z. e., looms 1n which thewarps are wound on normally fixedspools arranged on skewers;

in this class of looms, since the warp spools.

do not normally rotate, a loop is maintained in each warp by a weight,the loop afford ing the slack necessary to permit the takeup to beeffected as the weaving proceeds. Heretofore, the supporting means forthe warp supply spools has been arranged to project from the back of theloom. The consequence of this arrangement was that much space has beenlost which I have dem onstrated can be saved, with the result that myinvention makes it possible to increase the number of looms on a floorby about forty per cent. This I accomplish by arranging the warp supplymeans on a superstructure surmounting and connecting the upper portionsof the frames of two looms disposed back to back, the said sup portingmeans, as well as the take-up mechanism, for each loom being disposedbetween the vertical planes occupied by the front and back of said loom;further, the means for guiding the warps are so arranged that at theback of each loom the warps appertaining thereto extend substantiallyvertically, approximately in a plane coinciding with the vertical planeof said back of the loom, whereby a clear aisle is left between the twolooms and the warps are perfectly 'rangement of looms constructed inaccordance with my invention; Fig. 2 is a vertical Specification ofLetters Patent.

the superstructure of the loom, the same appearing on a larger scalethan in Fig. 1; Fig. 3 is a plan view of the levers controlling the warpsupply spools and their supporting means; Fig. 4 is a fragmentaryelevation of the superstructure and a portion of the mechanism carriedthereby as Seen from the right or left in Fig. 1; Fig. 5 is a detail ofthe part of the means for controlling the warp supply spools; Fig. 6 isan enlarged vertical transverse sectional view of a fragment of one ofthe looms and of the improved glass bar bracket mechanism;

and, Figs. 7 and 8 are detail views of one of the breast beams.

In the drawings, a designates the frames (of usual construction) of twolooms disposed back to back, each loom having a takeup mechanism Z), abreast beam 0, a glass bar bracket mechanism d, a lay or battenstructure e, shuttles f, and a means g, of any desired construction, foroscillating the lay structure and reciprocating the shuttles. The framesa are surmounted by a superstructure h, which is preferably bolted orotherwise removably secured to the frames a; said superstructure maycomprise two sides 2' connected by three upper and three lower rods jhaving nuts for clamping the sides and rods together. Thus, the improved weaving machine involves the employment of a frame whichcomprises distinctframe units (one for each of the twin looms) disposedback to back and a superstructure rigidly connecting the upper rearparts of said units.

The sides 2' of the superstructure 71, support the upper and lower beamsZ, the faces an of the sides a converge upwardly, and it is againstthese parts that the beams Z are secured, so that the two lower beams .Zare farther apart than the two upper beams. To

each upper and lower beam is secured a' grooved heads 9 of the spoolsand have at tached to them the flexible connections t which, since theframe a is inclined as in Fig. 4, extend upwardly clear of each other.

A plurality of brackets 21. are supported on the rods j in parallelarrangement, the same have bearings 4; which fit over the rods andhaving bolted to them clips 20 which coact with the bearings to securethe brackets adjustably to the rods. At each end each bracket has anupwardly extending arm m which carries a bearing rod y for rollers aover which the warp threads A pass from the spools 79. Each arm w alsosupports a fulcrum rod 1 for a set of levers 2, each lever beingfulcrumed between its ends on the rod and the inner arms of the severallevers in each set being preferably of dilferent lengths. The flexibleconnections 25 are connected to the outer ends of these levers, andtheir inner ends carry the grooved rollers 3 over which the warp threadsrespectively pass on leaving the rollers a. On other bearing rods 4.supported by the brackets u in a plane below the rods 1 are journaledother grooved rollers 5, the warps extending from these rollers straightdown to the glass bar bracket mechanism d, the relative arrangement ofthe rollers and the glass bar bracket mechanism d (to'be described)being such that the respective sets of warps stand close to the verticalplane occupied by the back of each loom. Between corresponding rollers 5and 3, each warp extends under a grooved roller 6 which is journaled ina hook shaped bracket 7 supporting in its depending hook a weightcarrier 8; the portion of each thread between the rollers 3 and 5 thusforms a loop to afford the necessary slack. Each lever 2 has its innerend formed with a downward projection 9 whose end is bent offhorizontally, as at 10 (Fig. 5), said end being adapted to be engaged bythe corre spondingly bent olf end 11 of the bracket 7.

Thus, as the weaving proceeds, the slack formed by the loop in each warpthread Wlll gradually be taken up. Ultimately, the bracket 7 will engagethe corresponding lever 2 and, tilting it, will produce a relaxation ofthe frictional action of the brake-band s on the corresponding spool, sothat the spool will be released and the slack represented by the loopwill be increased by the consequent fall of the weight. action of thelevers to cause the release of the spools when the levers are shifted bythe rising weight-carrylng bracket 7 may be increased by connecting eachlever with a roll 12 carried by the bracket u by a spring 13; thisspring has the further function to reduce the strain on the warprepresented by the weight of the lever when the bracket 7 is elevatingsaid lever, in effect balancing the lever at that time. The lower set ofrods j may be utilized to sustain wire nettings or The sensitiveness ofthey the like 14 to catch a weight and protect the weaver against injuryshould the weight fall owing to the breaking of the warp.

Referring, now, to the glass bar bracket mechanism (Figs. 1 and 6) ahorizontal rod 15 is arranged in the back lower portion of upper end, aswell as with a rearwardly proj ecting lug 20; said lever structure alsocomprises upper sections 21 which fit in the grooves 18 and are securedto the sections 17 by bolts 22 penetrating the slots 19, the lower endof each section 21 having a rearwardly projecting lug 23 whereby, bymeans of a bolt 24 and nut 25, the upper section is anchored to thelower section. Each upper section is recessed at the back at its upperend, as at 26, and it has its upper extremity turned rearwardly,'as at27, an angle iron 28, connecting the several sections 21, being fittedover the upper ends of said sections 21 and secured thereto by bolts 29.The vertical web of the angle iron 28 is received by the recesses 26 andit has vertical slots 30 receiving threaded studs 31 which project fromthe frame a and have nuts 32 between which the angle iron is clamped. Byadjusting the nuts, the entire lever structure may be adjusted forwardor back on its fulcrum 15. A series of brackets 33, each having a jaw 34receiving the edge of the horizontal web of the angle iron and adownwardly projecting leg 34', secured to the angle iron 28 by clamps35, are carried by the lever structure and in these brackets arearranged the glass bars 36 under which the warp threads pass forward tothe breast beam 0. By adjusting the nuts 25 on bolts 24, the glass barsmay be disposed at any desired elevation; and by adjusting the nuts 32,the lever structure may be set forward or back at the proper angleaccording to which of the glass bars are actually engaged .by the warps,it being understood that according to the character of the goods beingwoven it will sometimes be the back bars 36 and sometimes the forwardones around which the warps pass.

I have shown in Figs. 7 and 8 an improved breast beam constructionhaving for its purpose to produce a flattening of the threads of thewarp, whereby to fill up spaces which of hardened steel or the like)having a sharp edge 38. This bar is removably supported on the breastbeam by clips 39 in which it rests, the clips having hooked portions 40which engage over the rear side of the channel iron forming the breastbeam and feet 41 bearing against the under side of the channel irons.

Claims for the improved glass bar bracket mechanism shown in detail inFig. 6 I have made the subject of a separate application filed May 3rd,1910, Serial No. 559122.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In a weaving machine, the combination of a frame comprising spacedframe-units disposed back to back and a superstructure surmounting andconnecting the upper portions of said frame-units, and a warp-supplymeans and a take-up mechanism arranged in each frame-unit substantiallybetween the vertical planes occupied by the front and back thereof, saidwarp-supply means being carried by the superstructure, substantially asdescribed.
